IVIOLDBOARD ATTACHMENT FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 611,349, dated September 2'7, 1898.

Application filed February 2, 1898. Serial No. 668,826. (No model.)

To a, whom it may concern:

vBe it known that we, FRANK BORGE and J osnrrr E. CLARY, citizens of the United States, residing at Newman, county of Stanislaus, State of California, have invented an Improvement in Moldboard Attachments for Flows; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to a novel means for attaching moldboards to plow-standards and means for readily reversing them.

It consists, essentially, in forming or fixing upon the back of the moldboard a slotted lug or projection,which is adapted to pass through the lug of the standard and to be locked thereto by a key passing through the slot, the projection being so placed with reference to the top and bottom of the moldboard and the latter so shaped that it can be, reversed by simply removing it and reversing it, then securing it again in place.

The invention also comprises details of construction,which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a view of the attachment.

Fi 2 shows the moldboard separated. b

The object of our invention is to provide a means for readily attaching, removing, and reversing the moldboards of plows, and it is especially adapted to that class of gang-plows locally known as the Stockton gang-plow. In this class of plows A is a standard,which is attached to the plow-beam and which has a lug B projecting to one side for the purpose of attaching the moldboard thereto.

The moldboard O is made of the proper curvature and maybe of wrought or cast in this opening, projecting through it sufficintly so that the slot E is exposed behind the lug.

F is a key which is inserted and driven into the slot, thus drawing the moldboard firmly against the front of the standarddug and lockin g it firmly in place. \Vhen thus locked, one of the acute angles is presented to the ground essentially in the line of travel of the front edge of the standard, the edge of the mold board meeting the landside, so as to make a clean out when the plow passes through the ground. The other acute angle is at the top and at the opposite side of the plowshare, as shown.

The shape of the two ends of the share is such that by removing it from the standard it can be reversed and the bottom becomes the top, the top taking the place of the bottom, so that whenever the share has become dull it may be reversed by simply knocking out the key, reversing the moldboard, replacing, and again looking it in place, the time occupied being very short.

Having thus described our invention,what We claim as new, and desire to secure by Letters Patent, is

1. The combination of a plow-standard having a lug projecting substantially at right angles from one side thereof, a reversible moldboard fitting said lug and means for locking the moldboard to the lug.

2. A plow-standard having a lug and support projecting substantially at right angles from one side thereof, and having an opening formed in it, in combination with a moldboard fitting said lug and having a slotted projection onv its back adapted to be passed through the opening in the lug, and ameans engaging the slotted projection and locking the moldboard to the lug.

I A plow-standard having alug or support projecting from one side with an opening made through it, a moldboard having a projection centrally upon the back with a slot therethrough, said proj eotion fitting the opening in the standard-lug, and a key fitting the slot and locking the moldboard to the support.

4. The combination of aplow-standard havand adapted to be reversed so that either edge ing a lug proj eating substantially at right anmay be uppermost. gles from one side thereof, and provided with In Witness whereof We have hereunto set an opening, a moldboard fitted to said lug and our hands. 5 having a slotted projection centrally placed upon its back and adapted to pass through the opening in the lug, and a key passed through the slot in the projection and adapted Witnesses: to detachably look the moldboard to the lug, J ULES LAIN, IO said moldboard having a rhomboidal form J. BLUM.
